Alter the Number of Cached Logins

After you enter your username and password in Windows NT, the computer contacts the domain controller, verifies your identity, and logs you in to the system. However, when the domain controller is unavailable, NT checks for previously cached logins. If there aren't any cached logins, you aren't allowed to log in.

By default, NT remembers the 10 most recent login attempts. To change this number, edit the registry. Here's how:

1. Open the Registry Editor (Regedit.exe).
2. Go to HKLM\SOFTWARE\Microsoft\WindowsNT\CurrentVersion\Winlogon.
3. Find the CacheLogonsCount Value Name with REG_SZ Data Type. If it doesn't exist, you can create it manually.
4. Change the Value Data to any number between 0 and 50. Using 0 will disable cached logins. If you type any number greater than 50, the OS will cache only 50 login attempts.
5. Close the Registry Editor.
6. Restart the computer.
